Should preamp be left turned on?


Following a prior question, what's your view in the case of a solid state preamp (I have the Spectral DMC30SL...switch is in the back, I think).

I'd leave it on unless there was a danger of electrical storms, in which case I'd switch it off and unplug it. Otherwise I see only benefits in leaving it on ... longevity, sound (maybe), and no downsides (unless it's got a huge power consumption, which is very unlikely).
I leave my integrated amp on all the time, but I turn the volume to minimum and select an unused input when it is not in use.
I've been leaving ss electronics continuously powered up for 35 years through three systems and have yet to need a repair.
I second SeanDTaylor: Longevity is a benefit only for low power - which a preamp is. For high power Class A or tube amps, this point would be ambiguous (Pass X600 springs to mind). I leave mine on all day and off only at night as, what I feel, is a balance between thermal loading and thermal cycling. Arthur
